Migrating SBS2k8 to Windows 2012 (Domain Controller/File server) & Windows 2012 (Exchange 2016).
Posted on 2016-08-15
I am in the final phases of migrating a Windows 2008 SBS to a Windows 2012 environment with Exchange 2016.
- I have already migrated to Exchange 2013. Exchange 2007 has been uninstalled from SBS2k8.
- FSMO is still being held by the SBS2k8. I plan to migrated those roles as the final step.
I am now in the process of migrating from Exchange 2013 to Exchange 2016. Part of this process requires that the Domain and Forest functional level are at 2008. I see that it is still running at 2003 functional level.
1. Should I be concerned about upgrading Forest/Domain functional levels to 2008 if the SBS 2008 is still in the environment?
2. Would it be a better approach to first decommission the SBS2k8 and move FSMO? I would really like to have Exchange 2016 up and running and then leave the decommissioning of the SBS2k8 for the end.
Thanks in advance.
